macOS 10.13 High Sierra release date, news and features


Now that macOS 10.14 Mojave is arriving on our Macs in less than a week, macOS High Sierra is living out its last day as the primary Apple OS – so let’s take this opportunity to dive into everything you need to know about the outgoing macOS High Sierra.

While macOS 10.13 High Sierra has faced its own fair share of problems like password vulnerabilities and other security exploits – most macOS 10.13 problems have been fixed, and we’ve had a very positive experience over the last year. Plus, that new file system and those built-in photo editing tools go a long way towards making up for macOS 10.13 High Sierra’s release date issues.

The major issue faced by macOS 10.13 is familiar – just like what Mountain Lion faced as it followed Lion, it brings in a wealth of new features, but fails to innovate in any real way. Still, macOS Mojave looks like it’s going to switch some things up when it introduces iOS apps like News and Stocks.

While we wait for macOS Mojave, here is everything you need to know about today’s macOS High Sierra.

Cut to the chase

  • What is it? The 2017 edition of Apple’s Mac operating system, macOS
  • When is it out? Available to install now
  • What will it cost? macOS High Sierra is free to download

macOS 10.13 High Sierra release date

Apple revealed macOS 10.13 High Sierra at the WWDC 2017 keynote, which is no surprise, given Apple’s tradition of announcing the latest version of its Mac software at its annual developer event.

Yet, it wasn’t until September 12 that Apple revealed that the full release of High Sierra would launch little more than a week later, on September 25. There was a developer version of the operating system you could enroll in leading to the final release, but luckily that’s no longer required to take advantage of the latest features found in macOS 10.13.

What is likely to be the final version of macOS High Sierra, macOS 10.13.6 has been released. Alongside a few bug fixes, it integrates Airplay 2 into iTunes (though you’ll also need to update iTunes to take advantage of it). You can download the update today from the Mac App Store. The bigger news here is that Apple released a bug fix with this update that should stop the new Core i9 MacBook Pro from thermal throttling.

However, if you’re interested in testing out new features and updates before everyone else, Apple is still supporting its beta program, which will let you download and install macOS Mojave now.

At the same time, it now uploads all Messages to the cloud and replaces iBooks with the newly rebranded ‘Books’ app. There’s also been a sweet smoke cloud wallpaper added across all systems that was formerly available only on the iMac Pro

For everyone not willing to jump into untested waters, macOS High Sierra is still the most current OS, as we wait for macOS Mojave’s release on September 24. So, you have less than a week to wait for the latest and greatest macOS. 

macOS 10.13 High Sierra features

Beyond the Hackintosh users being reasonably worried about the newly enforced security checks on EFI firmware automatically implemented each week, Apple has revealed a number of awesome new features with macOS 10.13 High Sierra. 

These include improvements to Safari – which will now stop ad-tracking and auto-playing videos in their tracks – and a more expansive Spotlight Search in the Mail App. Additionally, when you’re composing emails, the app now allows split view for the compose window – and, to make matters better, it uses up to 35% less disk space.

The Photos app has also been updated, with a better sorting tool to boot. All of this is accompanied by a better layout, improved facial recognition thanks to neural networks, and improved syncing across all Apple devices – this all makes macOS High Sierra’s photo experience better than ever before.

Editing tools, too, have seen improvements, in turn making it easier than ever to enhance the quality of your photos without learning the ins and outs of Photoshop or Camera RAW. And of course, you can count on Instagram-like filters being a part of this.

One of the biggest changes that comes with macOS High Sierra is with the file system. It’s ditching the HFS – which Apple has used for around 30 years, and is now using the Apple File System (APFS) instead. 

Every Mac that has been upgraded to macOS High Sierra will receive these file system updates automatically with the exception of those sporting Fusion Drives and older HDDs. Similarly, all new Macs will ship pre-formatted for APFS.

To be exact, APFS is a 64-bit file system that supports native encryption and faster metadata operation. This may all sound a bit techy, but the bottom line is that this will make your Mac feel a lot faster, while also being more secure and more transparent about the nature of your files and folder contents. Unfortunately, this comes with the caveat of Apple’s confirmation that 32-bit apps will be discontinued in later versions of macOS High Sierra.

The update also brings HEVC, or H.265, video compression to the Mac. Apple claims that this new standard can compress video files 40% more than the previous-generation H.264 standard. The end result will be faster video streams at higher resolutions – ahem, 4K – and smaller video files sizes when stored locally.

VR finally comes to the Mac

One of the biggest bits of news surrounding macOS High Sierra is that it will finally bring support for virtual reality headsets officially. Namely, the HTC Vive and Steam VR will work with Macs running the new OS this autumn.

However to use such a device, you’ll need at least a 5K iMac or MacBook Pro – or, any Mac that can run the new OS with an external GPU solution. Support for such devices comes part and parcel with macOS High Sierra, but won’t be an active function until later this year.

The good news is that macOS High Sierra comes with a helping of refinements to its graphics API that make up for the scarce GPU support. Metal was a step forward for hardware-accelerated 3D graphics, but with Metal 2, Apple promises less strain on the CPU as well as proper machine learning and better Xcode profiling/debugging in macOS High Sierra.

Perhaps more important, though, is the fact that MoltenVK was recently brought to Mac by Khronos Group. An implementation of the open-source Vulkan API, it’s said to bring frame rate gains of up to 50% in Dota 2. As it’s cross-platform, too – being supported by Windows and Linux as well as Apple’s devices – MoltenVK is likely to be more widely adopted by creators.

macOS 10.13 High Sierra compatibility

Fortunately, in the act of creating a macOS iteration that only moderately shakes things up, the barrier to entry didn’t change at all. As long as you’re rocking one of the following Mac models, you’ll be good to go with macOS High Sierra on day one:

Bear in mind that if you want to take advantage of the High Efficiency Video Coding (HEVC) benefits posed by macOS High Sierra, you’ll need a Mac donning – at the very least – an Intel sixth-generation Skylake processor. Unfortunately, that discounts everything released prior to 2015, but on the bright side, everything else macOS High Sierra brings to the table is fair game.
